Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544952, here are decompositions:
- 11 + 31544941 = 31544952
- 29 + 31544923 = 31544952
- 53 + 31544899 = 31544952
- 73 + 31544879 = 31544952
- 181 + 31544771 = 31544952
- 193 + 31544759 = 31544952
- 233 + 31544719 = 31544952
- 239 + 31544713 = 31544952
Showing the first eight; more decompositions exist.
